A Cross-Validation Study of Sequential-Simultaneous Processing at Ages 2 1/2-12 1/2 Using the Kaufman Assessment Battery for Children (K-ABC).
Kamphaus, Randy W.; And Others
The development of two types of mental processing (sequential and simultaneous) in preschool and elementary children was examined in this study. Specifically, the aims of the study were to develop a revised set of tasks based upon previous findings (Naglieri, Kaufman, Kaufman, & Kamphaus, 1981; Kaufman, Kaufman, Kamphaus, & Naglieri, in press) in order to (1) provide independent cross-validation of the existence of sequential and simultaneous processes in children by factor analyzing this battery of tasks for a large, nationally representative sample; (2) assess the construct validity of the Kaufman Assessment Battery for Children (K-ABC); and (3) study developmental changes in the two processes across the preschool and elementary school range. A national sample of 2,000 children from 22 states participated in the study; participants ranged in age from 2 1/2 to 12 1/2 years and were stratified by sex, race, socioeconomic status, geographic region, and community size. The subjects were first divided into 11 age groups (100 children each at ages 2 1/2 and 12 1/2, and 200 children for every 1-year interval from 3 through 11) and then were individually administered the 10 mental processing subtests of the K-ABC. Analyses of the 11 groups produced two significant factors per age with clear-cut sequential and simultaneous dimensions emerging for each group. The results expanded current knowledge of the nature of the processing dichotomy and supported the construct validity of the K-ABC. (Author/MP)
